FEED-GAGE PIN.

Specificationof Letters Patent.

Patented Aug. 11, 1908.

Application filed July 19, 1907. Serial No. 384,508.

To all whom it may concern:

Be it known that I, MELBURN P. MORSE, a citizen of the United States,and a resident of Ballston Spa, in the county of Saratoga and State ofNew York, United States of America, have invented certain new and usefulImprovements in Feed Gage Pins, of which the following is aspecification.

My invention relates to an im rovernent in feed gage pins such as areattac wd to the tympan sheet of a printing press, and its object is toprovide a simple and efficient pin which has many advantages over thoseknown in the art. I

I will describe my invention in the following specification and pointout the novelfeatures thereof in claims.

Referring to the drawings, Figure 1 is a plan view of one form of thegage pin which I ave invented. Fig. 2 is a side elevation of the samestructure. Fig. 3 is a sectional end view of the pin shown in Figs. 1and 2, the section being taken on the line 33 of Fig. 1. Fig. 4 is aplan view and Fig. 5 a sectional side elevation of another form of myimproved gage pin, the section in Fig. 5 being taken on theline 55 ofFig. 4. Fig. 6 is a plan view and Fig. 7 is a side elevation of a simpleform of my invention. Fig. 8 is a plan view of another modification ofmy invention, and Fig. 9 is a side elevation of the form of gage pinshown in Fig. 8.

Like characters of reference designate corresponding parts in all of thefigures.

10 designates the body portion of my improved pin, from one end of whichone or more prongs 11, 11 extend longitudinally.

These prongs are of the peculiar form shown in the drawings. The part ofthe prong which is adjacent to the body portion of the pin'is in theform of a straight flat shank 12.

ts outer end is pointed as at 13, while the portion intermediate thestraight flat shank and the point is curved downward as at 14. This is afamiliar construction, and it not only facilitates the insertion of theprong or prongs in the tympan on the impression platen, but as thecurved portion 14 is designed to rest upon the outer surface of thetympan it tends to push the outer end of the body portion of the pindown against the tympan. This part of the operation is illustrated inFig. 2 in which the tympan is represented by dotted lines and isdesignated by the numeral 30.

At the opposite end of the body portion 10 of the pin one or moreshorter prongs 15, 15

are provided. These are bent back under the body portion so that theyare parallel with the prong or prongs 11. These too are arranged to bepushed into or through the tympan 30 and assist in holding the bodyportion of the gage pin securely in place upon the tympan, and also toprevent it from slipping laterally or from being pushed up away from thetympan.

A loop or strap 16 is placed upon the surface of the body portion 10.This is preferably stamped out of the metal of the body portion itselfin the manner shown in Figs. 1, 2 and 3. At either side of this strapthe sides of the body portion may be cut away as shown at 17, 17 as-thiswill facilitate one part of the operation of the device.

20 designates a guiding surface which is provided with the usualoverhanging lip 21 along its upper edge. The height of this guidingsurface and the amount of projection of its overhan ing lip may bevaried according to the work to which the pin is to be applied.

22 designates the lower portion of a sliding tongue which is attached tothe portion which forms the guiding surface 20 or which is an integralpart of the latter. The rear end of this tongue is bent back upon itselfat 23 to form the upper portion 24 of the tongue, and its other end isbent downward to form a shoulder at 25 which is arranged to contact withthe part 22. The sliding tongue is preferably constructed of springmetal and the upper and lower portions thereof are so formed that theyhave a slight tendency to spread apart.

The sliding tongue is arranged to be placed over the top of the bodyportion 10 of the pin and under the strap 16. It may be inserted fromeither the left-hand or the right-hand side of the body portion of thepin according to the position of the pin on the platen in relation tothe work to be guided. The tongue and its connected guiding face may bemoved a desired amount toward or away from the body portion 10. Thetendency of the two parts of the tongue to spread apart will cause it tobe held firmly in position, and in order to remove all possibility ofthe tongue and its connected guiding surface slipping in relation to thebody portion of the pin, I prefer to corrugate or roughen the up ersurface of the part 24 of the tongue anc the under surface of the strap16 with which the part 24 comes in contact.

The strap 16, of course, holds the two printing press the body portionis secured'to" the tympan in such a position as to bring the guidingsurface 20 into approximately the position required for guiding thework. The guiding surface may then be adjusted by hand to a greatnicety. The bent portion or shoulder 25 Will press the part which formsthe guiding portion tightly down against the tympan so that the latterwill successfully stop the thinnest sheet of paper at the desired point,and this pressure will be resisted by the prongs 15, 15. The recesses17, 17 which are cut out of the sides of the body portion are providedfor the purpose of allowing the lower portion 22 of the sliding tongueto be pushed downward by the shoulder 25 and to prevent the sides of thebody portion of the pin from interfering with this function.

It is to be noted that the means which I have provided for holding thepin upon the tympan are at right angles to the thrust of the materialupon the guiding face. It may also be seen that there are no holes madein the tympan by the pin near the guiding surface, upon the roughenededges of which the work would so easily catch. The extreme ease ofadjustment and the distance through which such adjustment can be madewithout changing the position of the pin upon the tympan are alsovaluable features.

In the form of my invention shown in Figs. 4 and 5 the body portion ismade in the form already described, but the strap 16 in this case is setlaterally across the body portion, and a recess 17 is cut in the endrather than in sides of the body portion. The guiding member and itssliding tongue are like those already described, and the operation issimilar except that with this form of gage pin the thrust is parallelwith the holding prongs and, of course, this pin can not be set out soclose to the edge of the tym- In the modification of my invention shownin Figs. 6 and 7 the body portion 10 is provided with but one longcurved prong 1 1 and one short prong 15, and the guiding face 20 isintegral with the body portion of the pin. This form of gage pin may beset out upon the edge of the tympan and thus make possible the printingof a full form of type.

Figs. 8 and 9 show a similar form of gage pin, but in this case the bodyportion is pro vided with one long curved prong 11 and two short prongs15.

It is evident that in these forms of pins in which the portions whichform the guiding surfaces are integral with the body portions theguiding surfaces cannot be changed from one side of the pin to the otheras can be done with the pin shown in Fig. 1. For this reason I makethese one-piece pins left and righthanded in order to make themadaptable to all kinds of work. I have in the drawings shown one ofthese pins with the guiding surface on the left-hand side of the bodyportion and the other with the guiding surface on the right-hand side ofthe body portion to illustrate this feature.

I have illustrated several forms of my invention to show that I do notlimit myself to any one form of construction or design.
